# ui_text.ludic — text: text-fit shrinks a line to its chip down to a least size and then cuts it with
|
|
# an ellipsis; line-height as a multiple and in px; an em reads the font size the element ends with
|
|
# (set later in the rule, or by a later rule); a sheet's own rule wins a tie with one it imports.
